| mastication | The process of chewing food in preparation for swallowing and digestion. (12 Dec 1998) |
| masticator nerve | <anatomy, nerve> The smaller root of the trigeminal nerve, composed of fibres originating from the trigeminal motor nucleus and emerging from the pons medial to the much larger sensory root, to join the mandibular nerve; it carries motor and proprioceptive fibres to the muscles derived from the first bronchial (mandibular) arch, including the four muscles of mastication, plus the mylohyoid, anterior belly of the digastric, and the tensores tympani and veli palati. Synonym: radix motoria nervi trigemini, masticator nerve, portio minor nervi trigemini. (05 Mar 2000) |
| masticatory | 1. Subserving or pertaining to mastication, affecting the muscles of mastication. 2. A remedy to be chewed but not swallowed. (18 Nov 1997) |
| masticatory apparatus | The organs and structures primarily functioning in mastication: the jaws, teeth with their supporting structures, temporomandibular joint, muscles of mastication, tongue, lips, cheeks, and oral mucosa. Synonym: dental apparatus, masticatory apparatus. (05 Mar 2000) |
| masticatory diplegia | Paralysis of all the muscles of mastication. (05 Mar 2000) |
| masticatory force | The motive force created by the dynamic action of the muscles during the physiologic act of mastication. Synonym: biting strength, masticatory force. (05 Mar 2000) |
| masticatory muscles | Muscles arising in the zygomatic arch that close the jaw. Their nerve supply is masseteric from the mandibular division of the trigeminal nerve. (12 Dec 1998) |
| masticatory nucleus | <anatomy, nerve> A group of motor neurons innervating the muscles of mastication (masseter, temporalis, internal and external pterygoid muscles) and the musculi tensor tympani and tensor veli palatini. The nucleus lies in the upper pontine tegmentum medial to the main sensory nucleus of the trigeminus. Synonym: nucleus motorius nervi trigemini, masticatory nucleus, motor nucleus of trigeminus, nucleus masticatorius. (05 Mar 2000) |
| masticatory silent period | A pause in electromyographic patterns associated with tooth contacts during chewing and biting; a part of the complex feedback mechanism of mandibular control involving receptors in the periodontal ligament and muscles. (05 Mar 2000) |
| masticatory spasm | Involuntary convulsive muscular contraction affecting the muscles of mastication. (05 Mar 2000) |
| masticatory surface | That portion of the surface of a denture that makes contact or near contact with the corresponding surface of an opposing denture or tooth. Synonym: facies occlusalis dentis, facies masticatoria, grinding surface, masticating surface, masticatory surface, occlusal surface. (05 Mar 2000) |
| masticatory system | The organs and structures primarily functioning in mastication: the jaws, teeth with their supporting structures, temporomandibular joint, muscles of mastication, tongue, lips, cheeks, and oral mucosa. Synonym: dental apparatus, masticatory apparatus. (05 Mar 2000) |
| mastich | 1. <botany> A low shrubby tree of the genus Pistacia (P. Lentiscus), growing upon the islands and coasts of the Mediterranean, and producing a valuable resin; called also, mastic tree. 2. A resin exuding from the mastic tree, and obtained by incision. The best is in yellowish white, semitransparent tears, of a faint smell, and is used as an astringent and an aromatic, also as an ingredient in varnishes. 3. A kind of cement composed of burnt clay, litharge, and linseed oil, used for plastering walls, etc. <botany> Barbary mastic, a lofty tree (Bursera gummifera) full of gum resin in every part. Origin: F, fr. L. Mastiche, mastichum, Gr, fr. To chew, because of its being used in the East for chewing Alternative forms: mastich. Source: Websters Dictionary (01 Mar 1998) |
